The Nike Football Training Camp series will continue outside of Dallas on Sunday. Athletes will trek to Allen, Texas, the home of one of the most impressive high school stadiums in the country. Allen Eagles Stadium, a $60-million facility, opened last year and featured nearly 22,000 fans watching Texas powers Allen and Southlake Carroll clash.

Here are five storylines to watch on Sunday.

Talented DBs aplenty

It’s been said on multiple occasions that the 2014 class may be one of the strongest in years at producing big-time defensive backs in the region. The battle for defensive back MVP has the potential of being extremely competitive with players such as Laurence Jones (Monroe, La./Neville), Jamal Adams (Lewisville, Texas/Hebron), Tony Brown (Beaumont, Texas/Ozen), Steven Parker (Jenks, Okla./Jenks) and Arrion Springs (San Antonio/Roosevelt) expected to be in attendance. Chris Hardeman (Houston/Alief Taylor) has committed to LSU, while Dylan Sumner-Gardner (Mesquite, Texas/West Mesquite) and Armani Watts (Forney, Texas/North Forney) have pledged to Texas A&M. Deionte Thompson (Orange, Texas/West Orange-Stark), a 2015 prospect, has verbally committed to Alabama. All of the DBs will have their shots in one-on-one drills against equally talented ESPN Watch List receivers such as Malachi Dupre (River Ridge, La./John Curtis), K.D. Cannon (Mount Pleasant, Texas/Mount Pleasant) and Texas commit Lorenzo Joe (Abilene, Texas/Cooper).
